THE father of murdered football prodigy Kiyan Prince has told for the first time of his grief and anger over the violent death of his son.

Former professional boxer Mark Prince, 36, wept as he described how his life has been devastated after 15-year-old Kiyan "met the Devil".

He admits he flew into an uncontrollable rage when he heard the youngster had been stabbed as he left school.

He punched holes in a hospital wall and fought off two police officers trying to console him.

Cops feared he would try to seek revenge.

But in an exclusive interview with the Mirror, youth worker Mark told how he now wants to ensure his son's death was not in vain by campaigning for a change in laws covering knife crime.

Comforted by Kiyan's mum Tracy Cumberbatch, 39, the father-of-five said: "Kiyan was too good and too innocent. He could only see the good in people.

With tears streaming down his face he added: "He didn't understand that people would want to hurt him. He would ask me why.

"I said 'Son, don't be going in to save people, you will be the one who will end up getting hurt'. Both his mum and I had that fear about Kiyan.

"But he really met with the Devil that day. There was nothing we could do."

Just two weeks before his death on May 18, Kiyan and his dad talked of staying away from trouble as they sparred outside the family's home in Edgware, North London. Mark and Kiyan, a pupil at the London Academy school, had trained together for five years.

Kiyan, a popular pupil, was tipped by coaches at QPR as a star of the future.

But when his mum asked him who his football idol was, he said he didn't have one - his only hero was his dad.

Mark said: "The person who stabbed Kiyan didn't just kill him, he killed me, his mum and all of his family as well.

"Something has been taken away. We'll never be the same." Mark and Tracy, a teaching assistant, hope to keep their son's memory alive by setting up a foundation in his name and backing reforms to end Britain's blade culture.

Tracy said: "The Government needs to do something seriously - not just a knife amnesty.

"They should look at the knock-on effect of something like this on the family."
